Virginia Tech - Graduate Research Assistant

About

I graduated with a B.S. in Electrical Engineering from the Beijing University of Posts and Telecommunications (BUPT) in Beijing, China, in 2018. Later, I obtained an M.S. in Computer Science from Arkansas State University, Arkansas, USA, in 2021. Currently, I am working towards a Ph.D. in Computer Science at Virginia Tech, under the supervision of Prof. Wenjing Lou.
